Amritsar September 13, 2022– Ladakhi girl, Deachen Angmo, Phd scholar from the Department of Botanical and Environmental Sciences, a research scholar at the Guru Nanak Dev University Amritsar  was awarded the “Best oral presentation award” at the international conference on “Waste Management and Recycling” held in Bangkok, Thailand.

            Deachen Angmo, presented her work on the conversion of sewage sludge into nutrient-rich organic fertilizer through Vermi-technology. And focused on the need for earthworm health in the soil   -“The earthworm has the potential to convert the sewage sludge into vermin compost which is rich in essential plant nutrients. The application of vermin compost from sewage sludge further enhances crop yield and provides defense against various plant diseases subsequently providing sustainable solutions to combat the burden of waste. Dr. Jaspal Singh Sandhu, Vice Chancellor of the Univ appreciated the research of Angmo. The research scholar said she greatly valued the opportunity provided by the university to her. She also thanked her supervisor Prof. (Dr.) Adarsh Pal Vig Chairman, Punjab Pollution Control Board, Patiala.

The research scholar found the management of Solid and liquid waste (SLW) as one of the serious problems with the increasing and fast-approaching water crisis. It is extremely essential to effectively treat the SLW before it enters the water bodies. The contamination of soil and water is increasing due to various activities, seeming to produce harmful gases, leachate, thereby affecting the environment and human health, and therefore, there is an urgent need for cost-effective, eco-friendly techniques like vermin-technology-using earthworms, like vermin-composting and vermin-filtration for industrial sludge, food waste, animal waste, into vermin-compost (nutrient-rich manure) which acts as a soil conditioner and purifies the wastewater.”

And further adds –“Excessive pesticides have contaminated soil leading to alteration in the structure and fertility of soil ecosystems leading to an imbalance between flora and fauna of the soil. The earthworm is an important soil macro-fauna and a key indicator species in the eco-toxicological risk assessment of pesticide-contaminated soil. “Neonicotinoids” have become the most extensively used group of pesticides in the world. As a novel neonicotinoids insecticide, “clothianidin” has been commonly utilized for crop protection with high biological effectiveness against different pests. However research showed its use had led to a significant decrease in body weight of earthworm, Cocoon number, cocoon weight, and hatchling production also decreased significantly.”
